They have so much life to them, feels like you could hear what they are thinking just looking at their expressions! Your style is unique and even the most simple sketch is great! You have such a sweet talent congratulations!
I have something to say. I don't know how you take cricism, but please don't take offense to this. I think you are an amazing artist and I really like your style or I would not be watching you, but we can all use a little crit once in a while and I noticed something about your work. I think the faces seem awfully similar sometimes, especially the noses. The noses always have flared nostrils. Perhaps you really like the look of this, but consider that not everyone's nostrils look like that. Otherwise, I think you capture motion and expression very well and I really enjoy your art.
these are juste some simply drawings i made some of them like an automatisme, that's why it could be some similarity between the characters'faces , the next gray pencil characters i will submit today will be a little more different.
When i make i comic i have to work on different faces, but there i agree some of them are similar, cause it's just an amusing drive ,and sometimes without intention.
